Hi all, I replaced the NiCd battery with a replacement NiCd rated as 3.6 V, 60 mAh. It reads 3.8 V on my multimeter.
I reassembled the components to test it again, and when I switch the memory power on the LCD immediately turns on without me pressing the power button. I'm still getting vertical lines and there is no response when I try to cold start. I'm a bit stumped. I didn't have any solder spillage and the battery polarity is correct. Any thoughts?
